Background: Quantitative and functional alterations of professional antigen-presenting cells (APC) in SIL suggest that these lesions may have a diminished capacity to capture viral antigens. Moreover, GM-CSF (whose production is decreased in HPV-transformed keratinocytes) is an essential factor for the migration of APC in cervical (pre)neoplastic lesions formed in vitro and transplanted in vivo on mouse. In this study we performed a phase I/II clinical trial in order to determine whether a local application of GM-CSF on cervical low-grade squamous intraepithelial lesions (LSIL) might increase the recruitment of APC into the epithelium and indirectly the viral antigen presentation to the immune system. Methods: Fifteen patients with LSIL (10 GM-CSF and 5 placebo) were enrolled in this study. Patients received 4 GM-CSF applications (or placebo gel) and were followed during 6-7 months. APC infiltration was quantified by immunostaining with anti-CD1a mAb. Cellular immune response was evaluated by using an IFN-gamma intracellular staining on PBMC stimulated in vitro with the E7 HPV16 protein and L1 HPV16 Virus-like particles (VLP). Hybrid capture was performed to semi-quantify the viral DNA in cervical brush specimens. Results: GM-CSF applications were well tolerated in all patients. No difference in the cytological/histological and viral parameters assessed at 2 and 6 months after the last application was observed between the GM-CSF and the placebo group. An increased number of CD1a+ APC was observed in 6/10 patients treated by GM-CSF compared to 1/5 patient in the placebo group. There was an increased immune response against HPV in the GM-CSF group showed by NK and T cells producing IFN-gamma. [less ▲]

Despite the problems they cause, biological invasions represent a great opportunity to study large-scale plant evolution, e.g. in response to changing climate. Senecio inaequidens DC. is an herbaceous perennial originating from South Africa. It was introduced as a wool alien in a few precise locations about one century ago and after a lag phase of several decades, started to spread rapidly throughout Europe and its contrasted climate. Our study uses common garden experiments to assess the differentiation of the species along both altitudinal and climatic gradients. Life history traits are measured and linked to climatic conditions of source populations. Results show that the species evolved along a climatic gradient from the Mediterranean to the high Pyrenean. This along-invasion differentiation can be linked to mean temperature evolution along the gradient and shows how an introduced species can potentially develop adaptations to new encountered thermic conditions in a length of time of several decades. How understanding the adaptive response of a plant to new climatic conditions will help anticipating the potential response of the flora to climate change is discussed. [less ▲]

The objective of this presentation is to discuss the participation of students at the University of Liège to the educational spacecraft project SSETI-ESEO proposed by the European Space Agency. SSETI students are now mainly involved in the ESEO satellite for which the University of Liège is in charge of the MECH work package. The students have to propose a design for the structure of the solar panels (including the geometry and materials) and their deployment and pointing mechanisms (including electrical circuits, motors, hinges and actuators). Through detailed finite element computations in the SAMCEF software, they have to verify the structural integrity of the panels during the launch phase and to guarantee a safe deployment once on-orbit. Another task is to ensure an appropriate orientation of the solar panels to collect the maximum power from the sun. An industrial partner specialized in the development of computer-aided engineering solutions, SAMTECH, and a research center, Liège Space Center (CSL), also bring their expertise to the project.

the origin of the LEODIUM project which stands for Low Earth Orbit Demonstration of Innovations in University Mode. This project aims to create student pico- or nano-satellites. There is a strong motivation coming from the students and from the academic members to promote space. Being unexperienced in complete satellite design, as a first step in this direction, we started working with the ESA funded SSETI association. At the moment, two teams of students are working on SSETI satellites. One is working as the MECH team which is in charge of the design of the sun-pointing solar panels of the European Student Earth Orbiter (ESEO) satellite mechanisms, the other team is working on the phase-A studies of the Narrow Angle Camera (NAC) which will be the core payload of the European Student Moon Orbiter (ESMO) satellite, both in collaboration with local industrials. The students are mainly working on ESEO and ESMO as part of their master thesis. In addition to that, two PhD students are in charge of the coordination of the teams (one for the ESEO team and another for the ESMO team). They will also be the link between previous and new students every times an overlap will occur and ensure that information is not lost during the transition. In this paper, we will describe the current design and the achievements on the ESEO solar panels and the ESMO NAC camera. Explanation will also be given on how the collaboration between the local student and the SSETI association is managed. Finally, we will briefly introduce the prospective for the LEODIUM project.

As part of the International Heliophysical Year in 2007, a large-scale campaign is planned to observe the UV auroras of Jupiter and Saturn with the Hubble Space Telescope (HST). In this talk we will provide an overview of the Saturn campaign. Previous HST observations of Saturn's auroras have greatly extended our knowledge of the processes that occur in the planet's magnetosphere. In particular, Saturn's main oval auroras vary much more than Jupiter's in terms of latitudinal position and extent, and have been shown to be correlated with the conditions in the solar wind. However, these campaigns have generally been limited by their short-term nature, and in order to establish exactly how the auroras depend on the solar wind we must make observations continually over at least one complete solar rotation. This is the goal of the 2007 campaign, in which Saturn will be observed for a period of 30 days in January and February. The timing is fortuitous since not only will the planet be in opposition, allowing near-Earth measurements of the interplanetary medium to be extrapolated to Saturn's orbit, the Cassini spacecraft will be in a position to obtain in-situ plasma and magnetic field measurements from the magnetosphere and solar wind. Cassini will also make observations of Saturn's UV and SKR emissions throughout the campaign, and the planet will be observed by ground-based IR and radio telescopes. Here we provide a brief review of our current understanding of Saturn's auroras, along with an overview of the coordinated observations planned at Saturn and the key science goals we aim to address.

Cassini's Ultraviolet Imaging Spectrograph (UVIS) has completed two years of study of Saturn's atmosphere and auroras. Two long slit spectral channels are used to obtain EUV data from 56.3-118.2 nm and FUV data from 111.5-191.3 nm. 64 spatial pixels along each slit are combined with slit motion to construct spectral images of Saturn, with sufficient spatial resolution to image Saturn's auroral oval when Cassini leaves Saturn's equatorial plane. We will present new images and time-series data from summer 2006. Detailed spectral models of molecular hydrogen auroral emissions that include hydrocarbon absorption and hydrogen self- absorption have now been compared to UVIS data. We are analyzing a UV spectral feature detected in an auroral oval image from 2005. The feature is an absorption feature concentrated inside the oval, at wavelengths dominated by reflected sunlight and acetylene absorption. The absorption feature appears as a broad absorption "scoop". One plausible molecule that has a similar absorption feature is benzene, which has a cross-section some 500 times larger than acetylene in this spectral region. Thus UVIS is sensitive to small quantities of benzene. Enhanced polar benzene has been previously observed at Jupiter and can be generated in coupled photochemical/auroral models. We will explore the uniqueness of this interpretation, and compare the inferred benzene abundances to results from complementary Cassini CIRS infrared observations. Additional out of the equatorial plane UVIS Saturn data planned for the coming months will improve the signal- to-noise ratio and spatial resolution on the auroral ovals and their interior. Coordinated observations with Cassini VIMS and Hubble Space Telescope are being scheduled for 2007. [less ▲]

The time evolution of the magnetotail topology during minutes preceding and following substorm onset is an important question of the magnetospheric dynamic. The substorm onset is a local and explosive phenomenon, which makes it difficult to describe with in situ data. In this study, we investigate this problem thanks the remote sensing data provided by the FUV camera onboard the IMAGE spacecraft. In the first part of this study, we use a set of IMAGE-FUV and GOES-8 simultaneous observations obtained during substorms periods to develop a model of the magnetic field elevation angle at geosynchronous orbit. In the second part, we use a set of 259 substorms observed by the IMAGE spacecraft between 2000 and 2002. Taking advantage of the global scale of the observations provided by IMAGE-FUV, we describe the time evolution of the magnetotail topology provided by the model. An interesting result shows that the field is symmetrically stretched around the onset position before the onset time and this symmetry is broken after onset, with a more important stretching duskward to the onset.

An extended campaign of observations of the UV auroral emissions from Jupiter and Saturn is scheduled for three periods beginning in Jan. 2007 and ending in late June 2008. This will be by far the most extensive series of remote high resolution imaging of planetary aurora to date, and should provide new physical insight into the cause and effect relationships governing the controlling processes for the giant planet auroral emissions. These observations will overlap with in situ measurements of local solar wind and magnetospheric plasma conditions by Cassini at Saturn in Jan. 2007 and by the New Horizons mission approaching Jupiter in Feb. 2007. The UV auroral emission brightness and distributions will also be compared with extrapolated estimates of the solar wind conditions near each planet from periods just before planetary opposition in Jan. 2007 (Saturn) and June 2007 (Jupiter). The HST observations will also be coordinated with ground-based observations of near-IR auroral and nonthermal radio emissions. This paper will give an overview of the program, including the schedule of HST observations and the schedule of known coordinated observations. While a preliminary schedule has been submitted for the HST observations, this schedule will be finalized only when the HST orbit is sufficiently well known for the periods of observation for detailed pointing to be specified. By the time of Fall AGU, it should be possible to show the detailed schedule and pointing for the Jan-Feb 2007 observations. The paper will include a presentation of the plans for the rapid reduction and distribution of the HST auroral images to the community. [less ▲]

A numerical approach is proposed to model the reverberated sound field in rooms. The model is based on the numerical implementation of a diffusion model enabling spatial variations of the sound energy within a room, unlike the statistical theory. The proposed method allows to take into account most of complex phenomena encountered in room acoustics, like mixed reflections on walls (diffuse and specular), low and high absorption on walls, atmospheric attenuation, fitted zones. Moreover, the model can be applied to complex geometries, like multiple coupled rooms of different sizes. In this paper, the model and its numerical implementation are first detailed. Then, an application is proposed for a complex geometry defined by multiple coupled rooms with fitting objects, including low and high absorption on walls, in terms of sound level and reverberation times. The main interest of the model is that such approach requires less computational time in comparison with common approaches like ray-tracing simulations. [less ▲]

The atmospheric CO2 mixing ratio has fluctuated widely over the Phanerozoic, according to the estimates from available proxy records. Because atmospheric CO2 is a major greenhouse gas, these fluctuations should have led to significant climatic variations. The "classical" view is indeed that atmospheric CO2 has been the main driver of the Earth's climate history. On long-term time scales, the atmospheric CO2 level is the result of the balance between CO2 inputs from volcanoes or oxidation of old organic carbon (kerogen) in exposed rocks and outputs through silicate weathering or organic carbon deposition. Existing model reconstructions of the Phanerozoic history of atmospheric CO2 are based on such budgets. Recent data and model experiments currently challenge these models. First, the carbon cycle may be more complex than represented in the earliest models. In particular, silicate weathering depends on numerous factors, which are not obvious to model or are poorly known over the Phanerozoic. Mountain uplift is one such factor, which has been much debated in the last decade. Lithology is another example: basalts weather much more rapidly than other silicate rocks and the emplacement of large basaltic areas on the continents may trigger glaciations. Continental configuration is also more important than previously thought, as indicated by recent model experiments on super-continent fragmentation coupling geochemical and climate models. Problems of "classical" Phanerozoic CO2 models are also well illustrated by the fact that the most recent estimates of CO2 degassing show very little variation between the Cretaceous and the present, a period when large changes in CO2 have occurred, whereas degassing is the most important forcing of CO2 evolution in long-term carbon cycle models. Second, CO2 is not the only driver of climate evolution. This obvious fact has largely been forgotten in Phanerozoic studies. What the proxies tell us on paleo-atmospheric CO2 is not always in line with what we know about paleoclimatic records. For instance, the proxies suggest relatively high CO2 levels during the Late Ordovician glaciations. Similarly, the Late Jurassic now appears to be colder than earlier thought, while again proxies suggest high atmospheric CO2 at that time. The mid-Miocene climate warming, which occurs simultaneously with a drop in CO2, provides another example. This latter change in CO2 is unanimously reflected in all proxies and, so, this decoupling between CO2 and climate cannot arise from uncertainties on the reconstructed CO2 levels or from dating problems, as might be the case of the former two examples. Other climatic drivers than CO2 clearly need to be considered. In this respect, vegetation- climate feedbacks have been completely disregarded in long-term climatic studies. Cenozoic cooling is, however, accompanied by a progressive transition from closed forests to more widespread grasslands and deserts on the continental areas, a change which must have had major impacts on the surface albedo and the water cycle.

This paper proposes a method to deduce the first four moments and the co-moments (with any other asset) of an option return. We consider the dynamics of an option-replicating portfolio of four basic assets: the underlying, two long-term options and a zero coupon bond. This approach allows us to capture the moments up to order four of the underlying and to linearize the option return. A numerical example illustrates some of the features and applications of this model. [less ▲]

Accompagner la mise en oeuvre d'e-projets s’apparente fréquemment à un défi de taille. Dans ce cadre, les apports de la théorie de la traduction sont susceptibles de s’avérer utiles à tout intervenant appelé à accompagner une démarche de réflexion et/ou d’implémentation d’une innovation technologique. En cherchant notamment à intégrer, en plus des éléments contextuels, les attentes, intérêts et enjeux des parties prenantes, ce courant entend mobiliser les acteurs autour d’un projet commun et favoriser la "construction" conjointe de l’innovation. Cette approche se heurte néanmoins à la définition a priori de certaines dimensions des e-projets subventionnés par des fonds publics, rendue nécessaire notamment pour rencontrer les attentes du pouvoir subsidiant. Accompagner des projets figés par des conventions n’est par conséquent pas sans entraîner son lot de difficultés supplémentaires pour l’intervenant, que nous entendons considérer à partir d’un retour croisé sur trois expériences récentes en la matière. Celui-ci nous autorise en outre à soulever dans notre réflexion la double question du rôle de l’intervenant et de sa marge de manœuvre dans le cadre de projets subventionnés ainsi que celle de la responsabilité des parties prenantes par rapport à leurs enjeux divergents.

This paper presents an intermediate approach between parametric shape optimization and topology optimization. It is based on using the recent Level Set description of the geometry and the novel eXtended Finite Element Method (XFEM). The method takes benefit of the fixed mesh work using XFEM and of the smooth curves description of the Level Set method. Design variables are shape parameters of basic geometric features like circles, triangles etc. The number of design variables of this formulation is small whereas various global and local constraints can be considered. The Level Set description allows to modify the connectivity of the structure as geometric features can merge or separate from each other. However no new entity can be introduced by the programme. A central problem that is investigated here is the sensitivity analysis and the way it can be carried out efficiently. Numerical applications revisit some classical (academic) benchmarks from shape and topology optimization. [less ▲]

An important part of IEA 34/43 is concerning validation of building simulation models. Analytical and comparative validation of multizone building simulation models are the object of Subtask B while empirical validation of models dealing with the shading, day lighting and cooling load interaction is targeted by Subtask C. For the first approach, the Multizone Building Component of TRNSYS (“Type 56”) was tested in a series of exercises ranging from analytical and simplified cases up to more complex situations where special features like presence of site obstructions, internal windows are taken into account. The good capabilities of TRNSYS Type 56 as well as its limitations were pointed out by the exercise and the results are discussed in the paper. In the second approach, a well-instrumented testing infrastructure (a test-cell) located at EMPA in Zürich, Switzerland was used to check the performance of TRNSYS regarding the solar processing features (calculation of diffuse radiation; repartition of solar radiation on vertical facades) as well as the dynamic behavior of the Multizone Building model in different shading situations: no shading, internal shading, external shading. High quality measurements corresponding to periods of 600h were generated for each of these situations and the simulation model was tailored to represent as much as possible the experimental conditions. In general, the behavior of TRNSYS was demonstrated very good. The influence of some specific features of Type 56, for instance concerning the calculation of the infrared exchanges, is illustrated in the paper. [less ▲]

Policy makers involved in innovation policy and scientists working on newly emerging technologies such as nanotechnologies, are confronted with three considerable challenges: a lack of distinct indicating directions of possible applications (strategic uncertainty), a lack of scientific knowledge (complexity) and the ambiguous reception of new developments in society. In this climate of uncertainty and ambiguity it is by no means clear for the actors involved how to innovate purposefully and constructively. In response to such problems and difficulties, the Flemish interdisciplinary research project 'Nanotechnologies for Tomorrow's Society' (NanoSoc) engages innovation networks where each actor contributes his (incomplete) views and perspectives and confronts them with those of others. The project brings together nanotechnologists, natural and social scientists, stakeholders, and citizens in the region of Flanders, Belgium, to discuss and steer future nanotech developments in three particular fields of nanotechnology development: smart environment, bio on chip, and new materials. This article first discusses the main challenges in innovating successfully with nanotechnologies, to then elaborate on how NanoSoc seeks to effectively address these issues through interdisciplinary reflective action research.

Organochlorinated compounds such as polychlorobiphenyls (PCB), dichloro-diphenyl-dichloroethylene (DDE) and dichloro-diphenyl-trichloroethane (DDT) have the characteristic to influence the endocrine system of many fish species and mammals and are thus qualified as endocrine disruptors. The objective of this project aims a better understanding of the effects of these compounds on the thyroid function of European seabass (Dicentrarchus labrax). Thyroid tissue and muscle of 46 seabass from the Aegean Sea in Greece (fished and aquaculture, n=15 and n=31, respectively) were sampled. The levels in PCBs, DDT and DDE were evaluated in the muscles of 30 individuals. The diameter of follicles and the epithelial cell heights were measured in each individual by optical microscopy. The concentration of the thyroid hormone T4 (thyroxin) was measured by Radio-Immuno-Assay (RIA). Finally, the potential relationships between these thyroid parameters and these organic compounds were investigated using factor analysis and multiple regressions. A significant relationship between persistent organic pollutants (muscular PCBs and DDT concentration) and the different thyroid parameters (diameters of follicles, epithelial cell heights and muscular T4 levels) could be observed. We cannot exclude the assumption that an endocrine disruption of thyroid gland related to these pollutants could be the origin of the modifications of these thyroid parameters. [less ▲]
